FusionHub Developer Portal: FUSION LAUNCHER API & MCP

Developer & Agent Integration Overview

FusionHub FUSION LAUNCHER provides high-performance machine-readable specifications, structured JSON REST endpoints, and Model Context Protocol (MCP) streamable tool manifests. Autonomous AI agents, automation pipelines, and gaming platforms can seamlessly integrate with launcher updates, telemetry, and multiplayer server directories.

Available Machine-Readable Specs

REST API Reference (v1)

All endpoints support cross-origin requests (Access-Control-Allow-Origin: *), negotiate markdown via Accept: text/markdown with Vary: Accept, Accept-Encoding, and return structured JSON payloads with standard rate limiting.

Rate Limiting & Self-Throttling Headers

To enable safe agentic access and prevent denial of service, all API endpoints include standard IETF RFC RateLimit headers:

RateLimit-Limit: 100
RateLimit-Remaining: 99
RateLimit-Reset: 60
RateLimit-Policy: 100;w=60
X-RateLimit-Limit: 100
X-RateLimit-Remaining: 99
X-RateLimit-Reset: 60
  

API Versioning & Deprecation Policy

FusionHub guarantees stable path-based versioning (/api/v1/) with a minimum 12-month deprecation warning window before any active endpoint is retired.

Deprecation signals are broadcasted via standard HTTP response headers:

Deprecation: false
Sunset: Wed, 31 Dec 2030 23:59:59 GMT
Link: <https://minecraft.fusionhub.in/docs#deprecation>; rel="deprecation"

Model Context Protocol (MCP) Live Handshake

Anthropic Claude, OpenAI ChatGPT, and local LLM agents can connect directly via Streamable HTTP at https://minecraft.fusionhub.in/.well-known/mcp.

Both GET (manifest introspection) and POST (JSON-RPC 2.0 initialize, tools/list, ping) are supported natively.
